Abstract
A wind and wave energy plant (1) comprises a windmill with a rotor (3) and a wave-actuated water pump that can drive a turbine whose output shaft is in driving connection with an electric generator. The windmill includes a tubular mill tower (2), which is firmly anchored to the seabed and encloses a storage tank between the sea surface and the mill rotor (3), which tank can be filled with water by means of the pump via a non-return valve, and from which water can be led to the turbine.

A wind and wave energy plant (1), comprising a windmill with a rotor (3) and a wave-actuated water pump that can drive a turbine whose output shaft is in driving connection with an electric generator, characterized in that the windmill includes a tubular mill tower (2), which is firmly anchored to the seabed and encloses a storage tank (22) between the sea surface and the mill rotor (3), which tank can be filled with water by means of the pump (12, 13, 14) via a non-return valve (21), and from which water can be led to the turbine (23).
A wind and wave energy plant according to any one of the preceding claims, characterized in that the turbine (23) and the associated electric generator (29) are arranged in the mill tower (2) under the storage tank (22), and that the pump (12, 13, 14) and the non-return valve (21) are preferably integral with the mill tower (2).
A wind and wave energy plant according to any one of the preceding claims, characterized in that the mill tower (2) has a foot section (6) in which the turbine (23) and the generator (29) are arranged centrally in continuation of each other, and in which a cast foundation (7) for the mill projects centrally in an upward direction, and that the pump (12, 13, 14) is a piston pump with one or more pistons (13) capable of moving up and down in an area enclosing one or more of the members:
- turbine (23), generator (29) or foundation (7).
A wind and wave energy plant according to any one of the preceding claims, characterized in that the pump piston (13) or pistons can be moved by a wave-actuated elongated driving means (4), such as a float, which extends substantially in a diametral direction in relation to the tower (2), and which is journalled rotatably around the longitudinal axis of the tower at the foot section (6) of the tower.
A wind and wave energy plant according to any one of the preceding claims, characterized in that the foundation (7) of the tower has a downwardly increasing diameter below the sea surface.
A wind and wave energy plant according to any one of the preceding claims, characterized in that the part of the external wall (15) of the tower (2) located at the sea surface is made of metal, and that means for electrical heating of this part of the outer wall are included.
